  Recycled AlSi2.4Mg cast alloys can be used directly in new cast products such as textile machinery parts and for structural engineering such as aluminum sidings and window frames. In this work, the modification effect of antimony (Sb) on the microstructure and tensile strength of recycled AlSi2.4Mg cast alloy was systematically investigated. Aluminum Piston scraps was melted in a furnace to form a melt composition. The melt was adjusted to form the present composition, consisting essentially of 2, 4, 6, 8, 10 and 12 gr addition of Sb. However, its effect as a modifier is more pronounce at 8 gr addition of Sb and caused refinement of microstructure, which led to increase in mechanical properties. It was obvious that Sb modify the coarse Si platelets into a more fibrous one. An optimal tensile strength of 82.59 MN/m2 was obtained. However, fractal analysis performed on the microg.. Read More»
